To all whom it may concern: c Be it known that I, LEONARD Amano, a

citizen of the United States, residing at` Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus for Honin Razors; and I do hereby declare the Scription of the invention, such as will enable othe'rs skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and ii res of reference marked thereon, which urm a part of this specification.

This invention relates to new and useful improvements in apparatus for honing razors and comprises mechanism of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described` and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which- Figure 1 is a perspective view of the apparatus. Fig. 2 is a top plan view. Fig. 3 is a side elevation. Fig. 4 is a perspective view of the razor holder. Fig. 5 is a side elevation of the form shown in Fig. 4. Fig.

6 is a detail view of a segment member andmeans for turning the razor at thel end of its throw. Fig. 7 is an edge view of the` hone showing the manner of pivotally mounting the same. v Fig. 8 is a slight modication of the invention showing the manner of holding a safety razor to be honed. Fig. 9- is a detail view of the modified form for holdin the safet razor. Fig. 10 is a detail view o a part o the invention, and Fig. 11 is a detail view of a tension means for regulating the pressure of the razor upon the hone.

Reference now being had to the details of the drawings by letter, A designates the base of the apparatus from which rise the flanges A which are apertured lat A2 for the reception of the rods B. The upper surface o said base has a curved groove or channel C adapted to coperate with means to be hereafter described for regulating the longitudinal movement of the razor as it is drawn back and forth over the hone. Mounted upon said rods B are the sleeves D and D',

the former of which is provided wit-h a vertically disposed cross-head D2. A shaft E' is mounted fat its ends in apertures in said sleeves and laffords means whereby the latter may be moved together back and forth upon said rods. Projecting from said base are -1 the bracket arms A3 in which are journaled ollowmg to be a full, clear, and exact dethe twosprocket wheels A4 and A5 upon .suitable istub shafts, vand A6 isa handle which is fixed to the stub .shaft upon which the sprocket wheel A5 is fixed. A sprocket chain F passes about said sprocket wheels and to one of the links lof the chain is fastened a pin Gr upon which is journaled a roller G" adapted to have a rolling movement within the slot of said cross-head fso that, when the crank A is turned continuously in one direction, the endless .sprocket chain carrying lthe-pin will cause the :sleeves to reciprocate back and .forth upon the rods B and which will cause the razor to be honed to move to its limit in opposite directions.

A :sleeve H is journaled upon the rod E and has an integral arm I-I projecting therefrom, the end of which is bifurcated, said arm having a 'recess H2 in its end, and H3 designates a recessed member similar in shape to the bifurcated part of the arm H and adapted to be clamped against the latter by means of bolts H4 to vform bearing members for the rockin member I which is adapted to carry the andle of the razor. It will be noted that said member I is provided with a transverse recess I'l which is preferably rectangular in cross section and provided with two hub portions I2 which are cylindrical shaped and form the bearings for said member. The bifurcated endoil said arm H and the member H3, having two concaved arms, is adapted to clamp about the hub portion I2 and hold the member I as it rocks therein. Integral with said member I is a gear segment I'3 through which the recess I extends and I4 designates a lug which is integral .with the gear segment portion and to which a rod I5 is pivotally connected. The other end of said rod I5 is threaded and passes through an apertured bearing member .I having an integral pin J projectin through a lug IL integral with the collar FI, said pin I being adapted to rock within the aperture'in which it is mounted.

An anti-friction roller M is mounted in the pin M projecting from the lug z, and is adapted to travel in the curved channel or groove C for the purpose of giving the razor a back and forth movement across the hone as the razor moves from one end to the other of the hone.

J am nuts J2 are mounted upon the threaded end of the rod H and serve as means for regulating the tension of a spring K which is mounted upon the rod I5 and bearing between the member J and the head Is upon said rod which is connected to the lug I4.

livotally mounted upon a pin N which projects from the member H3 is a gear segment N having an anti-friction roller N2 pivotally mounted near its lower end and the teeth N3 of said member are adapted to mesh with the teeth of the integral gear segment I3 so that, when the segment N rocks upon its pivot, a partial rotary movement may be given to the member I which carries the razor to be honed.

A Projecting from the member I is a rod O carrying resilient clamping jaws at its end andwhich are adapted to engage the handle of the razor, as shown clearly in Fig. l of the drawings, to assist in holding the same steady.

A set screw, designated by letter Q, is mounted in a threaded aperture in the member I and is adapted to bear against the handle of the razor and coperate with one of the walls of the recess I to securely hold the razor while being honed.

Stops S are fastened to the upper surface of the base portion and in the path of the anti-friction roller N 2 upon the pivot-al segment member N and serve to tip the latter as the razor approaches the limit of its throw in opposite directions, said stop being adapted to coperate with the pivotal segments for turning the razor. The rib A at one end of the base portion is provided with a notch a in which the pivotal segment is adapted to move as it is tilted by coming i in contact with the stop S near one end of the device. Y

A spring arm T is fastened to the cross a head l)2 and has a free end positioned underneath the arm H and provided for the purpose of causing the arm H to rise slightly in the act of the apparatus turning the razor g at the limits of its throws in opposite direction, this provision of the spring being to l prevent an uneven wear upon the hone as the blade turns. The hone, designated by letter R, has pintles R in its opposite ends, which latter are l preferably provided with a sharp bearing! edge which reduce the friction of the tiltl ing hone to minimum and to allow the hone i to automatically adjust itself to the razor being drawn against the surface thereof. Said hone is shown as being in la casing or box R2 and held therein by means of set screws R3. The pintles R', it will be noted, are mounted in recesses P formed in the bracket arms P which rise -from the base portion A.

In F igs..8 and 9 of the drawings, I have shown a slight modificationof my invention in which means is shown for adapting the apparatus for honing safety razors and in which drawings Ldosi nates the handle of a safety razor and L t e safety razor held thereto. L2 designates a holder for the handle L and comprises a metallic clip having two parallel walls, preferably lined with rubber L", and said holder L2 is of such a shape as to fit the recess I and, as the sides are thin and resilient, they may be held in clamped relation against diametrically opposite sides of the round handle of the safety razor by tightening the set screw Q..

In operation, the handle of the razor is inserted in the recess I and held therein by tightening the set screw Q, the blade of the razor lying flat against the surface of the hone. As the crank is turned, the anti-friction roller carried by the pin upon the sprocket chain will cause the two sleeves D and D', which are connected together by the shaft E and form a carriage, to move t0- ward the other end of the block or base. The anti-friction roller M moving in the groove or channel C will draw the sleeve I-I toward the sprocket chain and the razor blade will begripped and held by the apparatus connected to the integral arm I upon the sleeve H and will draw the razor with it and at the same time the razor will be drawn with its cutting edge forward toward the opposite end o`f thehone.' In Fig. l of the drawings, the part of the apparat-us represents the razor having been drawn to a position upon the hone in readiness for the blade to be turned over to make a return draw movement upon the hone.

lVhen the anti-friction roller N2 comes in contact with the stop S, the pivotal se ment N will be rocked upon its pivot and the intermeshin teeth of the two segments N and I3 wil cause the member I to rock within its bearings and reverse the razor blade. As 4the segment N swings over as it approaches its limit in one direction, it will engage the recess a and cut even with the flange A. As the roller carried by the pin upon the sprocket chain approaches the other sprocket wheel, it will turn about the same and return to its starting positionI without interference with the sprocket wheel, the roller G moving back and forth in-the slot of the cross head as the razor reaches its limit in opposite directions. As the arm H approaches its limit in opposite directions and as it moves toward the hone, its under edge will contact with the upper surface of the spring T and have a tendency to slightly raise the blade of the razor as the latter is turned upon its rear edge and thereby prevent uneven wear at the turning point.

By the provision of the coiled spring upon the rod K, the pressure of the razor to be ground may be. regulated by moving the nuts upon the threaded ends of said rod inl one direction or the other, the varying of the tension of said coiled spring causing the member I to be held in slightly different axial adjusted positions. As the razor is drawn back and forth upon the hone, it will be noted that the latter will tilt under the slightest pressure to conform to the proper bevel to be given to the cutting edge of the razor, the hone adjusting itself automatically to the razor and thus affording means for honing the blade evenly.

In honin a safety razor, the handle is placed withln the holder L2 with the rubber lining thereof gripping the round handle of the safety razor and which holder is adjusted in the recess and held -by the set screw in the same manner as shown in Fig. l of the drawings.

From the foregoing, it will be noted that, by the provision of an apparatus as shown and described, a sim )le and etiicient mechanism will be ati'or ed whereby razors of the ordinary or safety types may be held so as to cause a true and evenly ground cutting edge.
